To all whom lit may concern:

Be it known that I, FREDERIC WILLIAM CHARLES ScHNiEwrNn, a citizen of the United States of America, residin y in Everett, in the county of Middlesexi, in the State of Massachusetts, have invented certain new and useful Im rovements in Apparatus for Charging Cokevens, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to apparatus `for charging coke-ovens, having for its object to rovide for a rapid andlhomogeneous chargof the oven with coal. 4Generally speaking, my invention consists in roviding a horizontally-supported longitu ally-movable conveyer-trough, preferably mounted on a truck adapted to move in front of a bank of cokeovens and having means for pushing it into and retracting it from the ovens and providing, in connection with said trough and movable therewith, mechanism for moving fuel longitudinally through the trough, forcing it out ofthe end distributing it in the carry on the same ovens. Prcferab y provide for a feeding of truck a coal-bin and I the coal from the bin into the movable charging-conveyers, though any means for bringing coal to and delivering it into the conveyer may be employed without I departure from my invention; p v c Reference being now had to the drawings, in which my invention is illustrated, A indicates a sectional elevation of a horizontal coke-oven having, as shown, sectional doors B and B on the charging side.

C indicates a device or raising the upper portion B of the door or when the lower portion is secured to it for raising the entire door. D indicates coal charged in the coke-oven. E E are tracks nmning in front ofthe cokeovens.

F is a truck, .which may conveniently be oven. H is a coal-bin supported on the truck F. i

I I indicate aconduit leading from the discharge-aperture of the. coal-'bin to the horizontal conveyer-trough. A screw conveyer J is indicated in the portion I of this conduit G, indicating a motor for actuatinf` the screw conveyer. The conduits I I and conveyer J, together with the motor G', While convenient are not essential, as the bin H may be furnished with a discharge-openin as indicated in dotted lines at h, b which it will discharge directly into the horizontal conveyer.

K K K are supporting-bearings for the horizontal conveyer, preferably made, as shown, in the form of wheels, so as to dimin- .sh friction.

L is the horizontal conveyer-trough supported by the bearing-wheels K K, &c., and open on top, so as to permit the free delivery of coal to it irrespective of its position. ported on and a short distance in frontl of the end of the trough is a leveling device, ably a roller, as indicated at M. I also prefer to secure to the under side of the conveyer one or more supporting-rolls, as indicated-ait M', which will rest upon the top of the fuel of the first charging while the `conveyer is being introduced and withdrawn,

N is a screw conveyer working in the conveyer-trough L and actuated, as shown, motor G*,'supported on the rear end of the conveyer-trough.

Sup- I prefery bya" I have indicated the screw conveyer as working in the conveyer trough because it is, for. obvious reasons, the most convenient and racticable device. It must be undcrsto however, that I .to limit myself to any particular form of conveying mechanism, as there` are many wellknown devices which would operate in a substantially equivalent way to the wheel-conveyer.

O and O are .pulleywheels,`the wheel O being, as shown, driven by a motor, indicated at G.) Passing over the pulley-w eels O and O' is a rope P, the ends P and P* of which are fastened to the conveyer-trough at a considerable distance apart, and, as indicated in the drawings, obviously the rotation of the pulley O toward the right will 'times be inconvenient to retract the eonveyer from the oven, while its rotation toward the left will force the conveyer into the oven.

In use the end loi the conveyer would be thrust into the end of the oven, the feedscrew set in motion, and the coal delivered to the conveyer-trough either from -the bin H or any other source of supply. The conveyer would be forced gradually forward, filling the oven, for instance, to the level of the lower section of the door, and as it is forced in the supporting-roller will rest upon the top ofthe fuel, serving to support the conveyeli in position and also to conipact the first partial charge fed to the oven as the conveyer moves forward, thereby increasing the density of the coke produced. After this the conveyer is gradually retracted, still vdeliv- -erlng coal to the oven and filling it to the determined height, the leveling device M compacting thc coal in the oven as the conveyer is withdrawn and the supportingroller M again moving backward over the partial charge, supporting the end of the conveyer, as it is withdrawn 'and further compacting the coal.

4 In case of very long ovens it may someuse a conveyer of the excessive length required to extend entirely through such ovens. In such cases shorter conveyers may be inserted from both sides of the ovens, Working to and from the center.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. As a device for charging coke-ovens, a horizontally-movable conveyertrough in combination with conveying mechanism secured in the trough for feeding material along the same and means for forcing the trough and eonveyer mechanism into and retracting them from the ovens and-a'leveling device, as M, secured to the end of the conveyer-trough.

2. As adevice for charging coke-ovens, a truck movable in front of the ovens in combination with a conveyer-trough open at top supported and horizontally movable on the truck, a feed-screw rotating in said trough, means for forcing the trough and screw into and retracting them from the ovens, a conveyer arranged to deliver coal into the trough outside of the ovens and a leveling device, as roller M, secured to the end of the trough beyond the end of the screw.

3. Asa device for charging coke-ovens a horizontally-movable conveyer-trough in combination with conveying mechanism secured in the trough for feeding material along the same and means for forcing the trough and eonveyer mechanism into and reti-acting them from the ovens, and a supporting and coalcompacting device M secured to: the under side of the conveyer-trou'gh.

4. .As a device for char g coke-ovens-a horizontally-movable conveyer-trough in combination with conveying mechanism secured in the trough for feeding material along the same and means for forcing the trough and conveyer mechanism into and retract' them from the ovens, a levelingdevice M secured to the end of the conveyer-trough, and a supporting and coal-compactingdevice M secured to the under side of' the conveyer.- trough.
